Buckingham Palace, the King’s official London residence, is widely considered the world’s most valuable property, estimated at approximately $4.9 billion.

This iconic landmark is far from a typical dwelling, boasting 775 rooms and hosting 50,000 visitors annually for various events, including receptions, dinners, and state banquets, according to the royal family’s website.

This figure excludes the hundreds of thousands of tourists who visit each year. In 2023-2024, approximately 530,000 tourists visited Buckingham Palace, according to Statista.

Many visitors also witness the renowned Changing of the Guard ceremony.

For those interested in a closer look, guided tours of the state rooms are offered during the summer and on select dates in the winter and spring, as detailed on the Royal Collection Trust website.

Buckingham Palace has served as the official London residence of the UK’s monarchs since 1837, according to the royal family’s website.

Its 775 rooms include 19 state rooms, 52 royal and guest bedrooms, 188 staff bedrooms, 92 offices, and 78 bathrooms, according to the royal family’s website.

The palace features stunning spaces such as the White Drawing Room, the Throne Room, the Ballroom, and the 47-meter Grand Staircase, as well as the 39-acre Palace Garden.

The palace balcony has served as the setting for numerous royal public appearances.

Another contender for one of the world’s most expensive homes is Antilia.

Antilia holds the Guinness World Record for the “most expensive private house in the world.”

The mansion’s value is estimated between $1 billion and $2 billion, according to Architectural Digest India.

It is owned by Mukesh Ambani, chairman and managing director of Reliance Industries.

This 400,000-square-foot residence stands 570 feet tall.

Antilia’s 27 stories encompass multiple swimming pools, a spa, and a theater, according to Guinness World Records.

The property also features 168 parking spaces and three helipads.
